Troubling reports emerge before top Alabama defender enters NFL Draft

This could end up costing him a lot of money come draft time.

Tim Williams, the talented Alabama Crimson Tide defensive end, was supposed to be a mid first-round draft pick. At least that's what a number of mock drafts have predicted. Now, that's in jeopardy following a disturbing report from WalterFootball.com:

That is a serious allegation. Gregory, also projected as a sure-fire first-round pick, fell to the second round amid failed drug tests. Since then, he's been suspended three times by the NFL for violating its substance abuse policy, and is currently serving a one-year suspension.

Campbell's report said that Williams has had marijuana issues similar to Gregory's, and that could scare teams away, especially in a draft that's strong on edge rushers who could be taken in the lower half of the first round and into the second.

In addition to the issues that Campbell's report cited, Williams has had other off-the-field troubles. He was suspended for the first half of a game against Kentucky following an arrest for carrying a concealed weapon without a permit.
